Energy Tower: Power for 15 Earths? Researchers have designed a product that its inventors claim could easily produce between 15 and 20 times the total electricity the world uses today. Not only that, it could also be used as a desalination device and may be able to reverse the effects of global warming. Those are pretty big claims, but the researchers from the Technion - Israel Institute of Science seem confident that the "Energy Tower" could be a major solution to the world's problems. They've been working on the concept since 1983, and together have spent more than 150 man-years researching, designing, testing, and analyzing. As project founder Professor Dan Zaslavsky explains, the Energy Tower works on the basic principle of convection: hot air rises and cold air falls. The 3,000-foot tall tower, with a diameter of 1200 feet, would take advantage of the heavy falling weight of cold air.
Mistakes I’ve made part 3: Poor sacrificial accounting There was a time when I routinely refused car travel, in favor of my more sustainable bicycle. Not always, but I had a high bar—if it was bucketing down with rain and I had no plastic pants, this was not sufficient excuse for instance. I would sometimes decline a ride even when others were purportedly driving somewhere anyway, to avoid encouraging them to be ‘driving anyway’ more often. I did enjoy cycling, on a good day, but many days weren’t good.
What Is Clearcutting? Environmental Issues > Wildlands Main Page > All Wildlands Documents This method of logging can destroy an area's ecological integrity. Clearcutting means the felling and removal of all trees from a given tract of forest. One forestry expert refers to the practice as "an ecological trauma that has no precedent in nature except for a major volcanic eruption."
You have $8 billion. You want to do as much good as possible. What do you do? I sat in a San Francisco conference room a few months ago as 14 staffers at the charity recommendation group GiveWell discussed the ways in which artificial intelligence — extreme, world-transforming, human-level artificial intelligence — could destroy the world. Not just as idle chatter, mind you. They were trying to work out whether it's worthwhile to direct money — lots of it — toward preventing AI from destroying us all, money that otherwise could go to fighting poverty in sub-Saharan Africa. "Say you tell the AI to make as many paper clips as it can possibly make," Howie Lempel, a program officer at GiveWell, proposed, borrowing a thought experiment from Oxford professor Nick Bostrom. The super AI isn't necessarily going to be moral.

For the love of God, rich people, stop giving Ivy League colleges money Stephen Schwarzman — the billionaire CEO of private equity giant Blackstone who once compared the Obama administration's proposal to close the carried interest tax loophole to the Nazi invasion of Poland — has decided to give $150 million to Yale to build a performing arts center. The primary beneficiaries of this will be Yale students, and Yale students are stupid rich. Not as rich as Schwarzman (who's worth $13.2 billion, per Bloomberg, of which he's donating a little more than 1 percent), but rich.
The Searl Effect Generator - Ultimate Overunity? undefined Searl Effect Technology The Searl Effect Generator (SEG) is a magnetic diode, and what one may consider one of the original "Free Energy" Devices. The inventor of the technology is Professor John Robert Roy Searl of England. The SEG in essence is a composite ring made of an electron reservoir (a rare earth like Neodymium), a magnetized accelerator stage (Iron or Nickel), an electron flow regulator stage (Nylon 66 or Teflon), and finally, a paramagnetic layer (Aluminium or Copper). The design of the SEG is both beautifully simple and infuriatingly complex at the same time.
The quickest, funniest guide to one of the most profound issues in philosophy This is the most persuasive case for giving more money to lifesaving charities that I've read in years. And it's written from perspective of a frat bro. Tommy Maranges, better known as Philosophy Bro, is a national treasure. Searl Effect Generator (SEG) From PESWiki Artist animation illustrating the three rings with rollers. According to Searl, who built nearly two dozen of these in the 1960's, the electrons flow from the middle to the periphery where they can be picked up either as AC or DC current. The Most Efficient Way to Save a Life: Malaria Nets Last winter, William MacAskill and his wife Amanda moved into a Union Square apartment that I was sharing with several friends in New York. At first, I knew nothing about Will except what I could glean from some brief encounters, like his shaggy blond hair and the approximation of a beard. He was extremely polite and devastatingly Scottish, trilling his “R”s so that in certain words, like crook or the name Brooke, the second consonant would vibrate with the clarity of a tiny engine. MacAskill, I soon discovered, was a Cambridge-and Oxford-trained philosopher, and a steward of what’s known as effective altruism, a burgeoning movement that has been called "generosity for nerds." Effective altruism seeks to maximize the good from one's charitable donations and even from one’s career. It is munificence matched with math, or, as he once described it to me memorably, “injecting science into the sentimental issue of doing good in the world.”
Journey Into Amazonia Green Treasure - The Useful Plants of the Amazon Valley by Michael J. Balick, Ph.D. Since the earliest adventurers explored the Amazon Valley, their quest has been for its treasures -- minerals, oil, animal skins, precious stones and metals, to name a few. At times, they have succeeded -- gold, emeralds, petroleum, and other raw materials so important to Western civilization have been exported from this vast region. However, by "taming" the forest and extracting its wealth, biological diversity has become the victim.

Divers Free Whale and Receive Rewards of Love The Whale...If you read a recent front page story of the San Francisco Chronicle, you would have read about a female humpback whale who had become entangled in a spider web of crab traps and lines. She was weighted down by hundreds of pounds of traps that caused her to struggle to stay afloat. She also had hundreds of yards of line rope wrapped around her body, her tail, her torso and a line tugging in her mouth. A fisherman spotted her just east of the Farallon Islands (outside the Golden Gate) and radioed an environmental group for help. Within a few hours, the rescue team arrived and determined that she was so bad off, the only way to save her was to dive in and untangle her. They worked for hours with curved knives and eventually freed her.
How Effective is Fair Trade? When many of us think about improving conditions in the developing world, Fair Trade may be one of the first things to come to mind. But how effective is Fair Trade? Is paying a premium to slightly increase some farmers' income the best way to tackle poverty? Could our income be spent elsewhere more effectively?
